Female corn, gravid w slugs?

My first thought was that maybe she was going to lay slugs, but it was suggested she was overweight. I don't see a weight issue, her whole body is typical till the rear end. Any thoughts, shes not nearly as "loaded' looking today but nothing was found in her tank. She is unmated.

Well, whatever was causing the bulging has rectified itself, I think she was a bit backed up and when she went it helped. Her substrate was a bit stinky after wards so she got a good tank cleaning.

I'm glad you figured out the problem. She did have a significant amount of bulging there. :)
